provide, in combination with the rollers,

devices disposed conveniently to the work feeding position which will with slight pressure automatically throw the rolls out of engagement, thereby eliminating much of w the danger of the hands or other parts of the body being caught between the rollers. Specifically it is'my object to provide in a power driven wringer in which clothes are fed through between independently mounted rollers a releasingplate disposed conveniently to the position-in which the clothes are fed which is so constructed and seconnected with the mounting, for the engaging roller that even though both of the hands of the operator may be caught. between the rolls, pressure on the releasing plate with the arm or body will release or trip the mounting of one of the rollers sov that it will move out of contact with the other, so that any parts of the body which are pinched between the rollers may be" withdrawn without serious injury.

Furthermore, it is an important object of the present invention to so place the releas-v ing plate that when the fingers or clothing 40 of the operator are accidentally caught be tween the rollers, the feeding action will necessarily bring the hand or body into operating engagement with the release plate without voluntary or direct efiort on the part of the operator. y

In the ensuing disclosures I have illustrated an embodiment of my invention-in combination with a power driven wringer,

and efiect the release of the parts caught in which there is a driven roll and a frictionally engaging roller.

Referring to the drawing: Figure 1 is a front elevation of the roller mechanism in a power driven wringer. .Figure 2 is a side elevation of the parts illustrated in Figure l.

of the safety device showing the preferred type of tripping cam. g L g A wringer of thetype illustrated" comprises a stationary frame in which a driven roller 2 is mounted. The actual drive for the driven roller is not shownas the particular type of drive forms no part of my inven- '15 tion. The, drive may be by gears, belts, chains, or other well known mechanical constructions. The engaging roller 3 ismounted in an upper casing at the spindles 5 of the roller 3 being mounted in journal blocks so 6 which are compressed 'dpwnwardly by a spring 7 extending across Ithe casing L. A cam faced element 8 is journaled in the center of the casing 4 and extending from the cam element is a handle 9 by which the frictional engagement of the roller 3 may be regulated. Although I have illustrated a preferred type of wringer, it shouldbe understood that I. do not wish to limit myself to a wringer having an upper frictionally engaging, roller as the upper rollermay be driven by a gear train operated independently, or in conjunction with the driven roller.

mountedby means of bosses 11 on the ends of the plates which engage pins 12 secured in the frame 1, are disposed in'position. preferably on each side of the rollers so Figure 7 is a perspective view of an end A pair of releasing plates 10, pivotally that in feeding clothes between the muers mo. I

the work or the hands may rest on the plates 10. The releasing plates-in the embodiment illustrated may be used to serve a double duty of providing a suitable hand rest and also providing a simple safety device. It should be understood, however, that to provide a wringer with a hand rest is old and that my invention consists in the provision of a safety devide which may be'mounted entirely independently of the wringer hand rest, the only positive requirement being that the releasing plate be located conveniently to the work feeding position. While in the illustration I have shown a releasing plate on each side of the rollers the provision of a single releasing plate may in some cases be advisable.

In order to provide mechanism whichwill eliminate almost entirely all risk of the clothing or parts of the body becoming caught between the rollers'I have provided a pair of releasing plates each of which in the embodiment illustrated constitutes a hand rest so that either will co-operate with the mounting of the engaging roller and will with slight pressure release the tension on the spring 7 so that the engaging roller will automatically spring out of engaging position. e s

Referring particularly to Figure 4 it will be noted that the casing 4: is secured to bi-" furcated spring clips 13 whichhave apertures 13 in the bifurcated ends which are adapted to seat, on pins 14 which extend from the lower housingl. The releasing plates 10 have cam faced tripping lugs 16 extending from the bosses 11 which engage the ends of the spring clips so that when the releasing plate on one side is pushed down-' wardly the ends of the springs engaged by the cam lugs on that SldGrOf the wringer are disengaged and the spring 7 causes the easing 4 to swing on its engaged pivots which are the pins'l on the other side of-the housing 1. a 1

Thus it will be obvious that should an operator or his clothing become entangled all that is necessary is to push on the releasing plate to effect a complete disengagement. .Furthermore, upon re-engagement of the spring clips with the pins 14, the cam lugs are pressed downwardly due to the strength of the spring action of theclips and the plates are automatically reset for releasing action.

Although I have. shown but one embodiment of my invention, it will be understood that modifications can be made .without departing from the principles involved.

Having thus described my invention,

2. A clothes-wringer comprising a stationary frame carrying a driven roller, a complementary frame'mounted on the stationary frame and carrying an engaging roller, a spring carried in the complementary frame for forcing the engaging roller toward the driven roller, locking means for holding the complementary frame to the stationary frame against tension of the spring, said locking means also serving as a pivotal connection between the two frames permitting of the swinging action of the complementary frame to either side of the stationary frame, and means carried by the stationary frame for releasing the locking means.

3. A clothes wringer comprising a stationary frame carrying a driven roller, a complementary frame 'pivotally mounted on the stationary frame and carrying an engaging roller, a spring carried in the complementary frame for forcing the engaging roller towards the d riven roller, means for locking the complementary frame against pivotal action on the stationary frame, means mounted on the stationary frame, for releasing the locking means, said locking means also serving as a pivotal connection between the two frames permitting the complementary frame to swing to either side of the stationary frame.

4.
